Selecting the Measuring System
The actual position value system to be corrected is selected via the
respective bit of
P-0-0413, Axis correction control word
. It is only
possible to select one of the actual position value systems!
Available correction functions and their dependencies:
•
backlash on reversal correction
(depending on sign of velocity command value)
•
precision axis error correction
(depending on sign of velocity command value and on actual position
value)
•
position-dependent temperature error compensation
(depending on current temperature and on actual position value)
•
position-independent temperature error compensation
(depending on current temperature)
•
control-side axis error correction
(current, cyclic position correction value from control unit)
Note:
All position-dependent correction functions only take effect
after the position data reference was established for the
respective encoder (see "Establishing the Position Data
Reference" in chapter "Drive Functions").
The sign of the velocity command value always refers to the
load side, independent of the selected data reference (motor
shaft or load).
The sum of active correction values is displayed in parameter
P-0-0401,
Axis correction active correction value
. The value refers to the
encoder selected in parameter P-0-0413.
